Usage:
$obj = Location::Area::DoCoMo::iArea->create_iarea($id,$sid);
Arguments:
$id : Set full area code or main area code
$lon : Set sub area code (needed if you give main area code as $id)
Return Values:
$obj : Location::Area::DoCoMo::iArea object. undef if can't bind code to area.

#Specify datum or format:
$oAura->datum_wgs84->format_degree...
Names of methods are same with Location::GeoTool.
#Get boundary latitude/longitude array:
($sbound,$wbound,$nbound,$ebound) = $oAura->......->array;
Notice:
NTT DoCoMo's aura data contains a lot of inconsistencies.
There are differents between Aura boundary square, which is
defined by DoCoMo's summary data, and that is calcurated
from mesh data.
So, I add adjusted aura data which are calcurated from mesh,
you can use it.
If you want, you should use this module like this:
use Location::Area::DoCoMo::iArea qw(useAdjustedAura);

Get i-Area object list which are next to this area.
Usage:
@next = $obj->getNextArea;
Return Values:
@next : i-Area object list of areas next to this area.
Notice:
1.If there is the sea between one area and another, they are not next area.
This definition is based on NTT DoCoMo's.
2.DoCoMo's official data contains a lot of inconsistencies.
So, this module adjusts them.
